What is Logical Volume Management (LVM)?

Logical Volume Management (LVM) is a Linux feature that allows you to perform disk management through an abstraction layer that exists between the operating system and the physical drives within a system. With LVM, you can create logical volumes from your physical ones. You can then resize and delete them while your system is running and without the need of rebooting it. You can also use LVM to aggregate multiple drives and partitions into a volume group, which you can then divide into logical volumes.

Another feature of LVM is that you can create a striped volume, which will distribute I/O in parallel to the disks hosting the volume. This is a concept that is similar to RAID-0. LVM further gives you the ability to create a snapshot of a volume, in order to back it up while applications are still writing to it.

Today, most distributions of Linux support LVM.
